The accident happened around 4pm on the E6, south of Harpefoss in the county of Oppland, Southern Norway.
Police chief Atle B. von Obstfelder said to NTB: “At first it was reported that it was the 16-year-old son who was driving, but after some examination by the police at the scene of the accident, it was likely the mother driving.”
The mother who was in her forties died immediately, while her son was declared dead shortly after the crash. Both mother and son came originally from Vinstra in Norway.
The Kawasaki motorcycle was heading north on the E6, while the camper van was travelling southwards.
As to how the two vehicles hit, Obstfelder said: “The explanation from some of the witnesses suggests the motorcycle came over to the lane of the camper van, and that they collided.”
A man and a woman in their sixties from Vestlandet, Western Norway) were driving the camper van. The woman was lightly injured and was sent to the hospital of Lillehammer.
Police officer Arvid Røste said to NTB: “We continue the investigation [Wednesday], doing technical examinations of the vehicles and later questioning the witnesses. The man who drove the camper van and is uninjured will become a central witness.”
Røste added: “A crisis team is notified in order to take care of task personnel and the involved people.”
On the E6 the stretch between Hundorp and Harpefoss was closed for a period of time after the accident, but is now reopened.
